ERD Campaign for Matrix Acidizing With Coiled Tubing—Nkossa South and Nsoko Fields

In a field study directed at improved well intervention on horizontal wells, several horizontal wells were treated with<br>acidizing techniques using coiled tubing (CT). The study indicates that CT can be efficiently deployed to target depth in<br>highly deviated and horizontal wells using tools such as vibrators in combination with the effect of a friction reducer and<br>proven pumping techniques. The study emphasizes CT operation design and will provide for operators and services<br>companies common tendencies that may be encountered during those operations.
